FIREPLACE HEATER.

T o all whom Vit may concern.'

Be it known that We, Louisa MY.` Srnolrr and JOHN A. Sinnen, citizens-of. the United States, residing at Chicago7 in the/county of Cook and State of Illinois, have invented certain new and useful Improvements ina Fireplace Heater; and werde hereby declarethe following to be a full, clear, and Vexact description of the invention, suclrl as will l0 enable others skilled in the Eart to which it appertains to make and use the-same The object of the-invention is to provides. heating apparatus designed for arrangement infconnection With a fire place for the 'pur-` pose of furnishing heatlorthe room or apartment in which the fine place is located and also to `furnish heeft .through Water circnlation or steam tonother apartments or rooms; and particularly to provide a heating apparatus of `which the heating agency is electricity and of'ivhioh the construction is such as to give the appearance of a coal or log lire such as ordinarily rovided in open fireplace heaters, and to a ord efficient means for regulating the `heat tosuit .the requirement; and with'these objects `in View the invention consists in a construction, combination and relation of parts of which a 'preferred embodiment isshown in the acf companying dravviings7 it .being understood that 'changes .in form, pro-portion, rsize Jand details of construction and arrangement may be resorted 'to Within the. scope of the appended claims without departing from the principle involved.

In the drawings:

Figure 1 is a front View of a fireplace equipped with a heating apparatus embodying the invention.

Figure 2 is asvertical sectional View taken longitudinally threugh .or iparallel with the front of the iireplace to illustrate/the arrangement of the local'heatingapparatus and the coils Wherebyheat is ,communicated by circulation to other apartments.

Figure 3 is an end view of the fire place.

Figure 4 is a vertical sectional View taken centrally through the same in a. plane at right angles to that of Figure 2 as shown by the dotted line 44 of Figure 2.

Figure 5 is a horizontal sectional view of the fire place on the plane indicated by the line 5 5 of Figure 27 showing the heating unit in plan.

Figure 6 is a diagram showing the Wiring system.

Serial No. 4573224.

having a. grate 22 Whichsnpports a housing 23 of cement or suitable refractory material shaped exteniorly and colored to` simulate coal, logs or like fuel. within which islocatcd a, heating unit 24 and an `illuminating unit 25, said housing being porous or having openings therein thro-ugh which heat from the heating unit and light from thelighting unit inlay readily rind egress` the lighting unit preferably being of an electric type and having a globe orbnlb 26 under a tire like color screen 54 to give the appearance oit'. fire and thus carry out the idee that the housing represents a. bed of coals or logs similar to that usedL in the ordinary fire place.

In the jambe of the fire place are located the elements 27 of a radiator having an in len provided with a controlling valve 28 accessible at one end of there place frame by means of 'a removable ca 29. shown iin detail in .Figure 10 and` kpre erably held in place by means of springs 30 orthe equivalent thereof, the outlet or circulating cenneotion` of the radiator being indicated at V3l, andthe side elements thereof 'being connected by the uppenand ylower connecting pipes 32 and 33 which respectively span the lire piece above Iand below the opening 21 but within the zone of heat-radiated from the unit 24.

The heatin unit preferably consists of a plurality of e ements each having a core 34 of asbestos or like material provided with a Winding 35 consisting of resistance coils preferably of #21 resistance Wire, coiled to an inside diameter of 1/8 of an inch and the pitch of coils to be 5/64th of an inch. This heater is in circuit With a source of electrical supply represented by the battery 36 but which obviously may be the ordina house lighting system with which the lea s or conductors 37 are connected. Said elements of the heating unit are ,preferably arrangedin afrim as indicated in Figure 5 with side bars 38 connected by bolts 39 extending thrrouvh the terminals of the cores of the elements' which may as indicated in Figure T he provided with projections 40 o r the like7 for engagement with the sides of an opening 4l formed in the grate 22, and connected with each core, at opposite ends thereof are the clips 42,-preferably ofbre and 43 of metal respectively, .(theimetal for example being copper or` brass) the libre clip is provided with grass or copper screws 44 with washers and nuts for the attachment of the conductors which connect with the extremities of the resistance coils Wound upon said cores. One element; of the `conductor representing the circuitincluding the source of electrical supply is intercepted .by a switch 46, shown in detail in Figures 8 and 9, said switch preferably being of the rheostat t pe to provide for varying the number og resistance coils included in the circuit to correspondingly the degree of heat to be furnished by .the heating unit. In the construction of the switch shovvng-as above noted in Figures 8 and YEL theinovable element 4T thereof 1is adapted to .traverse contact strips 48, 49 `and 50 and carries tongues 51 for respective engagement `v'vith said Contact strips, saidltongues and strips having yielding terminals to insurge-lan efl fective closingr of the circuit, and stops 52 being provided to prevent reverse or counterclockwise movement of the arni 47` which is ac tuable by a suitable button 53 locatedat.

the front of the. fire place, for example be?- neath the fire place opening, or otherwise as may be preferred or foundmore convenient.

Also included in parallel with the conductors of the heating unit is .nnected the lighting or illuminating unit 25, above mein tioned.` of which` the light is designed Ato show thro-ugh the interstiees in the ho'usingr togive the appearance of burning coal, a colored screen 54. for` examplefbeing arranged cna suitable bracket 55 above said unit' to display a col-oredlighton the real Wall 560i the fireplace opening.

While the .above indicated :construction ofiswitch is ordinarily found convenient7 there may be circumstances under which a cylindrioaly foi-in of theswitehanaybe preferreld siidicatd inLlignief-li; wherein the contact tongues 56 are carried by a spindle 5'( to which is attached theknob or button 58,V said tongues being arranged in operative relation with the contact strips 59 Whi-cli form respectively the terminals of the branch conductors in circuit with the resistance coils of the different elements of the heating units. i i

Having thus described th'e invention, what WeV claim. is z- 1. `A `re place heater having an electrical heating unit, a refractory housing enclosing theY same, and a radiator manifold having elements arranged in the field of radiation of the unit and heated thereby.

2. A fire place heater having an electrical heating unit, a refractory housing enclosing the same, anda radiator manifold having elements arranged in the field of radiation of the unit and heated thereby, and connected by circulating conductors disposed respectively above and below the plane thereof.

3. A tire place' heater having an electrical heating unit and an associated lighting unit, a .refractory porous housing enclosing said units and a radiator manifold having elements arranged in the Held of radiation of the heating unit andheated thereby.

4. A re place` heater having an electrical heating unit and an associated lighting unit, a refractory .porous housing enclosing said units and a radiator manifold having elements arranged inuthe field of radiation of the heating unit and heated thereb-y,.the latter consisting of a plurality of-elements each having a refractory7 core provided at opposite ends With'fibre andllnetallio clips provided with binding `postsand a resistance coil winding embracing the'core.

5. A Bre-place heater having-an electrical heating unit, a housing enclosing the` same, and a radiator arranged in the lfield of radiation of the unit and heated thereby.

In testimony whereof we affix our signa tures in presence ot' two witnesses.
